RE: groups
Not really, no. I wouldn't be happy with either grouping. I practiced at ten yards with my 20 yard pin until I could get all my arrows touching. I practiced until I had most of my arrows touching at 20 yards also. You want to be precise in this game. You don't want to have to wonder if your arrow is going to hit where you aim, or ten inches to the left of where you aim. That's just me personally, but I wouldn't be happy with that.
